The 1080p resolution is new for Apple devices, and a lot of third party apps haven't been optimized yet to take advantage of the hardware. Same thing happened for the first few months when the iPhone 5 came out. Just give it time. As far as I can tell on my 6 plus, Hulu is optimized, but Netflix and YouTube are not. I'm not even sure if the iTunes movies allow you to download them in bigger than 720p yet. On iPad it does, but not iPhone yet. You can look in the App Store at each app you want to use and see under what devices it works with whether it's optimized yet. If it just says optimized for the 5, it's not yet. That's why some apps will still look fuzzy, have larger keyboards, and the carrier logo and bars on the top of your screen will get bigger when using them. Just give it time. It's not an Apple issue. Just happens whenever Apple brings out a super-secret product with new specs, and then the rest of the world has to catch up. 🙂
